There you go Dina. You could be quickly in New Orleans for a romantic or fun filled weekend if Obama's high speed train plan comes to fruition. Looks like you could get to New York City quickly. Sorry Daisy, there doesn't seem to be much in it for you.
I can't really comment on the plans without doing some research and I am not for bothering, except this.
I read elsewhere about the construction costs, and they are extremely high . There is no high speed rail culture in the US, unlike Europe where they are very experienced at high speed rail and do it quite cheaply. The French know how to do it well. Rather than reinvent the wheel, just get French engineers to come over to the US and get busy. I think it would cost less and you can be assured, it will work.
It is criminal that there is not a high speed train between Sydney and Melbourne. I have heard that it is the busiest flight corridor in the world. I have also heard it is the fifth busiest air corridor in the world. Take you pick, but regardless, how good would be a high speed train from Southern Cross Station to Sydney Central, via Canberra I suppose for the pollies.
As I said, I am not so familiar with the US, but surely for the cost of all this bits of proposed lines, a high speed train could be built to link New York to California, alternate the trains between 'Frisco and LA perhaps. New York Central to the west coast in comfort and much less time than the drive to the airport in heavy traffic at each end, no bother with parking and check in and security. Just a very fast trip on tracks from the east to the west of the US, and vice versa.
